Advection: supply to GB
Hypotheses
Winter and early spring cross-isobath transport of
copepods is largely caused by locally and event-forced
surface Ekman fluxes.
Transport paths differ between species and vary
seasonally.
Interannual variability in the source and number of
copepods delivered to GB in January and February will be
directly related to the interannual variability in the winds
over those two months.
Near-surface copepods will be deposited on GB because of
the reduction in the Ekman velocity caused by the sudden
deepening of the mixed layer there through tidal mixing.
